A power delivery controller includes a detection unit, a regulation unit, and a control unit. The detection unit has a detection pin and an enable pin, wherein the detection pin is used for detecting a power delivery consumer device. The regulation unit is coupled to the detection unit, wherein when the detection pin detects the power delivery consumer device, the detection unit is used for turning on the regulation unit through the enable pin, and after the regulation unit is turned on, the regulation unit generates an internal voltage. The control unit is coupled to the regulation unit for providing power to the power delivery consumer device according to the internal voltage. When the detection pin fails to detect the power delivery consumer device, the regulation unit is turned off.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A power delivery controller, comprising: a detection unit having a detection pin and an enable pin, wherein the detection pin is used for detecting a power delivery consumer device; a regulation unit coupled to the detection unit and an external power, wherein when the detection pin detects the power delivery consumer device, the detection unit is used for turning on the regulation unit through the enable pin, and after the regulation unit is turned on, the regulation unit generates a direction current (DC) internal voltage based on the external power; and a control unit coupled to the regulation unit for providing power to the power delivery consumer device according to the DC internal voltage, wherein the control unit does not provide operation power to the detection unit; wherein when the detection pin fails to detect the power delivery consumer device, the regulation unit is turned off, or the regulation unit and the control unit are turned off, and the detection unit is still turned on.
2. The power delivery controller of claim 1 , wherein the control unit comprises: a power source unit; an interface protocol unit for communicating power delivery specifications of the power delivery consumer device with the power delivery consumer device; and a policy engine for controlling the power source unit to provide the power to the power delivery consumer device according to the power delivery specifications of the power delivery consumer device.
3. The power delivery controller of claim 2 , wherein when the detection pin detects the power delivery consumer device, the power source unit is turned off until the interface protocol unit identifies the power delivery specifications of the power delivery consumer device.
4. The power delivery controller of claim 3 , wherein when the power source unit charges a battery coupled to the power delivery consumer device through the power delivery consumer device, the power delivery consumer device transmits a storage power percentage, a charge full state, or a stop charge state of the battery to the control unit, wherein when the control unit receives the charge full state or the stop charge state, the power source unit stops providing the power to the battery and the power source unit is turned off, or when the control unit receives the storage power percentage and the storage power percentage is greater than a predetermined value, the power source unit stops providing the power to the battery and the power source unit is turned off.
5. The power delivery controller of claim 1 , wherein the control unit is further used for generating a data transmission direction signal, wherein the data transmission direction signal controls data to be transmitted from a power delivery provider to the power delivery consumer device or from the power delivery consumer device to the power delivery provider, and the data are audio data or video data.
6. A power delivery controller, comprising: a control unit providing power to a power delivery consumer device, wherein the control unit comprises: a power source unit; an interface protocol unit for communicating power delivery specifications of the power delivery consumer device with the power delivery consumer device; and a policy engine for controlling the power source unit to provide the power to the power delivery consumer device according to the power delivery specifications of the power delivery consumer device; wherein when the interface protocol unit communicates the power delivery specifications of the power delivery consumer device with the power delivery consumer device, the policy engine is turned off or the policy engine and the power source unit are turned off; and after the interface protocol unit identifies the power delivery specifications of the power delivery consumer device, the policy engine turns on the power source unit, and controls the power source unit to provide the power to the power delivery consumer device according to the power delivery specifications of the power delivery consumer device.
7. The power delivery controller of claim 6 , wherein when the power source unit charges a battery coupled to the power delivery consumer device through the power delivery consumer device, the power delivery consumer device transmits a storage power percentage, a charge full state, or a stop charge state of the battery to the control unit, wherein when the control unit receives the charge full state or the stop charge state, the power source unit stops providing the power to the battery, and the power source unit is turned off, or when the control unit receives the storage power percentage and the storage power percentage is greater than a predetermined value, the power source unit stops providing the power to the battery, and the power source unit is turned off.
8. A power delivery controller, comprising: a control unit providing power to a power delivery consumer device, wherein the control unit comprises: a power source unit; an interface protocol unit for communicating power delivery specifications of the power delivery consumer device with the power delivery consumer device; and a policy engine for controlling the power source unit to provide the power to the power delivery consumer device according to the power delivery specifications of the power delivery consumer device, wherein the policy engine is turned off or the policy engine and the power source unit are turned off until the interface protocol unit identifies the power delivery specifications of the power delivery consumer device; wherein when the power source unit charges a battery coupled to the power delivery consumer device through the power delivery consumer device, the power delivery consumer device transmits a storage power percentage, a charge full state, or a stop charge state of the battery to the control unit, wherein when the control unit receives the charge full state or the stop charge state, the power source unit stops providing the power to the battery, and the power source unit is turned off, or when the control unit receives the storage power percentage and the storage power percentage is greater than a predetermined value, the power source unit stops providing the power to the battery, and the power source unit is turned off.
9. The power delivery controller of claim 8 , further comprising: a detection unit having a detection pin and an enable pin, wherein the detection pin is used for detecting the power delivery consumer device; and a regulation unit coupled to the detection unit and an external power, wherein when the detection pin detects the power delivery consumer device, the detection unit is used for turning on the regulation unit through the enable pin, and after the regulation unit is turned on, the regulation unit generates a DC internal voltage based on the external power; wherein the control unit is used for providing the power to the power delivery consumer device according to the DC internal voltage; wherein when the detection pin fails to detect the power delivery consumer device, the regulation unit is turned off.
10. The power delivery controller of claim 9 , wherein when the detection pin fails to detect the power delivery consumer device, the control unit is turned off.
